When creating a custom food, on the web, it would seem that I could just enter the % RDA off the food label... but the values I see when I add the food to my daily log don't make sense to me.

Example - I created a custom food with 100% RDA for all vitamin's and minerals...

When I add only this custom food item to my daily food log (on the web) and look at the nutrition tab, I see
- Vitamin D as 10.0 mcg which is 100% RDA.
- Vitamin E is 20.1 mcg, 15.0 mcg is the RDA, so 134%

various values seem to be direct interpretations of 100% being 10.0 mcg, but many values do not... this does not make sense.

Essentially there is confusion around the "Daily Values" found on food labels and the RDA graphs in FitDay. The US government uses Daily Values for the values on a food label. These values are picked by the government to be useful without knowing the person's age and gender. FitDay takes those numbers and turns them into an amount ( for example 100% of Vitamin C becomes 60mg).

FitDay displays RDA charts in our reports.Your RDA for a nutrient is a different government standard that takes into account things like your age and gender. These are things that the label couldn't take into account. So while the DV was 100%, your personal RDA may be 110% because you need less due to your age and gender.

This can be confusing, but I hope this helps

Wow....you just impressed me. I just noticed the same "problem" that the thread initially pointed out, and thought that Fitday was "broke". I entered "25% Magnesium" from the label, and when I entered that food, Fitday told me in the RDA chart that food was 50%. So it's calculating MY needs. Impressive!
